Tsirkin" , Christoph Hellwig , Jens Axboe , Hannes Reinecke , Nicholas Bellinger List-Id: linux-scsi@vger.kernel.org From: Nicholas Bellinger This is currently required for connecting to tcm_vhost in order to prevent the client LUN scan from detecting the same tcm_vhost WWPN on multiple target IDs.
